REFLECTOR-SUPPORTED LIGHT-SOCKET MOUNTING.

' Application filed April 15,1927. Serial No. 184,001. v

This invention relates to head lamps and particularly to the mounting of the light bulb support upon the reflector.

The chief object of the invention is to do v tachably but relatively rigidly mount a light bulb supporting socket upon a reflector and in a predetermined position so that a predeterminedrelation will always be obtained between the reflector and the bulb focus.

The chief feature of the invention consists in the provision of a light bulb supporting plug socket and detachably but rigidly mounting the same upon a reflector in predetermined position thru a. yielding interlock. 7

The full nature of this invention will be understood from the accompanyingdrawings and the following description and claim. 7

Fig. 1 is an elevational VlGXV of a proportion of a reflector plugsocket support and plug socket associated therewith. ig. 2 is a longitudinal sectional view taken on line 22 in the direction of arrows. Fig. 3 is an end or rear view. 7

In the drawings 10 indicates a reflector having a central aperture 11. A tubular sleeve 12 having a plural flange'portion 13-is positioned in the reflector. aperture whereby we s eeve is e "ii an 1 tv 2 r' "t z tl l 3 i 1 (il l ind lglll in chored to the reflector. Slidabl'yreceivable by the sleeve is a light bulb supporting plug socketlt having the J slots 15 which detachof a light bulb base 17 positionable in the plug socket and supporting the light bulb 18 with the filament 19. I

Inasmuch as the filament of the lamp bulb bears a definite relation to the focus of the reflector with respect to the characterof the beam projected thereby, it is essential that the plug socket 14 be positioned in predetermined relation relative to the reflector. The plug socket includes a relatively closed rear end 20 having the aperture 21 therein to permit the entrance of the current conducting wires to the plug contact not shown. To positively position the socket as aforesaid, said socket is supplied with a plurality of notches or slots 22, a pair being shown and diametrically arranged. The sleeve 12 is split or posite direction. p v p In witness whereof, I have hereunto affixed my signature.

slotted at 23 to provide a spring tongue 24 INDIANA which has an angular tooth 25 formed 'on the end thereof and receivable by a slot or recess 22 in the plug socket.

This constructionpermits the convenient" detachment of the plug socket from the reflee-tor by manually' actuating one of the springs 2 1 and 12 l, but fixedly. secures a relat-ively rigid mounting thereof and the posi tive positioning of the socket and reflector. in predetermined relation. Thru the formation of a second tooth 125 (reversely formed from that shown at 25) upon another tongue 1124, forward movement of a plug 'socketxin the sleeve is prevented by the tongue 12 1 since the wall of the slot 22 engages the-tooth Rearward movement of the socket is prevented by the tooth 25 of tongue 24 seatmg in the opposite slot 22 in the plug socket. The foregoing arrangement also prevents rotative movement between the socket and sleeve but permits forciblercmoval'of socket if the sameisdesired. p

The invention claimed is: I In a lamp structure, the combination with a reflector and a bulb having a filament, of means for removably supporting said bulb in fixed relation in respect to said reflector in cluding a tubular sleeve having a double flanged head extending. into and centrally of the reflector, said double flanged head adaptthe ed to embrace the adjacent portion of the reflector so as to securely unitesaid reflector and sleeve, a pair of oppositely disposed spring arms stamped out from the body of said sleeve and p1oviclecl;\vitl1 latching teethv on the free ends thereof, and a bulb receiving socket extending through said sleeve, the body of said socket being provided with openingsfor receiving said teeth and causing the same to interlock said socket and sleeve, 1 said latching teeth being arranged oppositely to each other whereby one of said teeth will prevent longitudinal movement between the l sleeve and socket in onedirection and the other tooth Wlll prevent FREDERICK w; CQ E NE Q movement in the op- I
